How Should a Polo T-Shirt Fit? Shoulder, Chest, Sleeve and Length

A polo T-shirt fits right when the shoulder seam sits on your shoulder bone, the sleeve band ends halfway down your bicep, and the hem stops at the middle of your trouser fly. If you can pinch 2.5 to 5 cm of spare fabric at each side of the chest, the size is correct.

Key takeaways

• The shoulder seam decides the size. If it drops past the shoulder bone, go one size down.
• The sleeve band should end mid-bicep and leave room for one finger underneath.
• Untucked, the hem should cover your belt and stop around the middle of the fly.
• Regular fit polos suit Chennai heat better because the gap at the chest lets air move.
• Wash cotton polos cold and dry them flat in the shade to keep the collar and length intact.

Where should the shoulder seam sit on a polo?

The shoulder seam should sit right on the bony point where your shoulder ends and your arm begins. This is the one part of a polo no tailor can fix easily, so check it first.

If the seam hangs 2 cm or more down your arm, the polo is too big and the whole top half will look slouched. If the seam rides up toward your neck, the polo is too small and the chest will pull across the buttons.

How tight should a polo be at the chest?

A polo should skim your chest without clinging to it. Pinch the fabric at the side of your chest. You want 2.5 to 5 cm of spare cloth on each side.

Less than that and the knit will show every line of your vest and stick to your back by noon in 34 degree heat. More than that and the fabric balloons when you sit, which makes your middle look wider than it is.

Look at the placket too. The two or three buttons should lie flat. If the placket bows open when you stand straight, the chest is tight.

How long should polo sleeves be?

Polo sleeves should end about halfway down your bicep. The ribbed sleeve band should rest against your arm with room to slide one finger under it.

A band that grips your arm leaves a red line after an hour and feels hot. A band that flares open with a 3 cm gap makes your arms look thin. Sleeves that reach the elbow belong to a bigger size.

How long should a polo be if you wear it untucked?

Untucked, the hem should fully cover your belt and stop around the middle of your trouser fly. Raise both arms above your head. If your stomach shows, the polo is too short for you.

Most polos have a split at each side of the hem and many have a slightly longer back. Both features exist so you can wear the polo out over chinos or jeans without it bunching when you sit.

If the hem reaches the bottom of your back pocket, it is long enough to tuck in and too long to wear out. Tuck it into chinos for a smart office Friday, or pick a shorter size for weekends.

How should a polo collar sit?

The collar should lie flat around your neck with both points resting on your collarbone. It should not curl up at the tips or stand away from your neck.

Wear the top button open. Closing every button works only for a deliberate retro look, and in Chennai humidity it traps heat at the throat. A collar that curls after a few washes is usually a sign of drying in direct sun or tumble heat, both of which you can avoid.

Should you choose a slim or regular fit polo in Indian heat?

Pick regular fit if you spend most of the day outdoors or on a two-wheeler. The extra room around the chest lets air move between fabric and skin, and sweat dries faster.

Slim fit makes sense if you are lean, work in air-conditioning and want a sharper outline. If you have a broad chest or carry weight at the stomach, regular fit will look cleaner because the fabric will not cling.

How do Derby's in-stock polos compare?

We checked our live polo T-shirts on the day this guide went up. All three are cotton in a regular fit and tagged for casual wear. The model in the product photos is 6 feet tall and wears size M.

Derby White Cotton Regular Fit Polo Tshirt. Check the shoulder seam and sleeve band against the points above when you try it.

White suits every skin tone and works under a navy blazer or with dark jeans. Pink sits well on wheatish and dark skin and looks softer than a shirt in the same colour. Red is the boldest of the three, so keep the rest of the outfit plain: dark indigo jeans and white sneakers.

If you are between sizes, the white and pink polos run up to 2XL, which gives heavier builds room at the stomach. Browse the rest of our T-shirts for round necks and henleys.

How do you keep a cotton polo fitting the way it did on day one?

Wash it inside out in cold water and dry it flat in the shade. Cotton knit can shrink around 3 to 5 percent in a hot first wash, and most of that loss shows up in length.

• Button the placket before washing so the collar keeps its shape.
• Skip the dryer. Heat curls the collar tips and shrinks the body.
• Never hang a wet polo by the shoulders on a wire hanger. The weight of the water stretches the knit and leaves bumps.
• Iron the collar on low heat from the underside if it starts to curl.

FAQ

Should a polo be tight or loose?

Neither. It should skim your body with 2.5 to 5 cm of spare fabric at each side of the chest.

Can I wear a polo to the office in India?

Yes, on casual days. Tuck a plain white or navy polo into chinos and add a leather belt and loafers.

Should I size up a cotton polo to allow for shrinkage?

No. Buy your true size and wash it cold. Sizing up gives you a dropped shoulder that never shrinks back.

Can I tuck a polo into jeans?

You can, but most polos look better untucked with jeans. Tuck them into chinos or trousers instead.

Which polo colour suits dark skin?

White, pink, red and navy all give strong contrast with dark skin. Muddy beige and grey-brown shades tend to flatten it.

What if the polo does not fit when it arrives?

Derby accepts returns within 7 days. Keep the tags on until you have checked the shoulder seam and length.
